Bush junior was a man who was not smart but knew he was not smart. His biggest mistake was listening to that psycho Cheney...It took him 6 years to realise Cheney was an agent of the arms industry and a devil spawn to boot...by that by time it was already far too late. Eventually he did wise up and was barely on speaking terms with devilish Dick in his last year.. Difference is Trump thinks he is the smartest bestest pwerson in any room. He has a really big brain...huge.
